USB CDC Drivers under Windows 7 - Automatic Install
Hi, I've searched the forum but I didn't find anything regarding this matter
I've been using Microchip CDC drivers in several projects under Windows XP and Windows Vista.
Now the problem that I have is that the Windows 7 version that come to my hands want's to perform an automatic install of the usb cdc driver.
When I plug my device (it is a microchip 18f4550 based hardware) windows recognizes that there's a device plugged, automatically searches for the driver and fails the installation.
In previous windows version the driver installer "prompted" a question to search in windows update or in a user folder. I always managed to get the driver installed with the second option, in fact our customers do that too, they search for the driver in the CD path and they do the installation smoothly.
This is not the case on windows 7 (at least with the version I have), the installation fails automatically without asking to search on a CD, USB or any other path.
If I go to device manager, the device is higlighted with an error , i click there and then I can choose where to get the drivers from and the installation completes ok.
So, this step do work but I want to know if there's a better way or an automatic way I can follow in order to install microchip driver properly. I don't want the final user to follow complex steps for such a simple process as it was until windows 7.
Thanks in advance
